Application filed November 28, 1816. Serial No. 133,982.

To all whom it may concern:

be it known that I, Howann D. COLMAN a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois.have invented certain new and useful In'iprovements in Yarn-CarrierSupports, of which the :tollmving is a specitieation.

Spools, cheeses or other yarn masses, when taken from the spooler orwinder on which they were produced, have heretofore been deposited insuitable receptacles for transportation to the warpcr creel. where theyarn masses were placed in position in the creel, oneby one. When thespools or cheese cores were empty, they were removed, one by one, "fromthe creel, and placed at points adjacent to the spooler or winder. Theseoperations necessitated much rehandling oi the yarn masses and emptyspools or cheese cores. One of the objects of this invention is toreduce the amount ot handling ot the yarn masses andcontainers, andavoid the possibility of injury to the yarn which is incident to theprevious methods of handling and transporting yarn masses. This objectis attained by constructing the warper creel with removable sectionsadapted to be used at the spooler 0r winder as a receptacle or supportfor the yarn masses when removed from the spooler or winder. andadapted. to be transported to and placed in the creel.

Another object of the invention is to provide a yz'trn-earrier supportwhich shall permit rotation of the yarn carrier with a minimum amount offriction.

The invention also relates to the further improvements hereinafterdescribed.

In the accompanying drawings Figure 1 is a fragmental. verticalsectional view of a creel embodying the features of my invention,showing a trident in place in the supporting :l"rame. Fig. 2 is avertical sectional view taken approximately in the plane of dotted line2 of Fig. 1. Fig. 3 is a fragmental longitudinal central scctional Viewof a spindle and rollers comprised in the trident. Fig. lis a sectionalview of the trident.

While the invention may be used in connection with various forms of yarnmasses, it is herein illustrated as embodied in apparatus for supportingyarn masses in the form of cylindrical chooses a. Each cheese consistsof yarn cross-wound upon a tubular core Z). In the illustrative :lormherein shown. the axial opening of the cheese core is defined byinturned flanges Z).

In the creel the cheeses are rotatably supported upon spindles 1. fourcheeses. in the present embodiment, being carried by each spindle. Thecheese cores are not mounted directly upon the spindle. but are carriedby rollers 2 which are rotatably supported upon the spindle. Tn theconstruction herein shown, each roller is formed of sheet metal. It"desired. ball bearings may be interposed between the roller and thespindle. In the construction selected for illustration. a sleeve 3 ismounted upon the spindle 1, the ends of said sleeve being" expanded toform ball races 4. Each roller 2 comprises inturned end flanges 5 whichare bent to form ball races 6. Between the. ball races 4; and (3 areplaced balls 7. Tuwardly ol the ball races 6 the roller is provided withan annular flange or lip 8.

To lubricate the ball bearings a small. quantity of oil :11 is placed ineach roller 2 before the roller is placed upon the spindle. the oilbeing; introduced through an opening 9 in the sleeve "i. The quantityoi? oil is such that the level of the oil never touches the sleeve 3whether the spindle is in horizontal or in vertical position. the oillevel be ng such that when the spindle is tilted at any angle. the oilnever reaches the lip 9. iv reason of the well-known tendency of oil tocreep over a surface. sutlicicnt oil reaches the ball bearings to keepthe latter properly luln'icated. than the cheeses are rotated. the oila: is spread over the inner periphery oi the rollers 2. and when thecheeses are stopped some ot the oil creeps over the flanges 5 and thelips 8 and thus enters the bearings. The lip 8 increases the distancethe oil must creep and thus reduces to the desired extent the amount ofoil that reaches the bearinns. llhe amount o'l oil that reaches thebearings at any ,efiven stoppage is so small that the supply containedin the roller lasts for a long time.

The opposite ends of each' roller are slightly reduced in diameter toprovide surfaces 10 for supporting the bearing flanges 6 of the cheesecores, these surfaces being connected to the remainder of the peripheryof the roller by means of annular tapering shoulders 11'. By reason ofsuch reduction in diameter the roller has a generally crowning formwhich prevents the cheese from moving laterally into contact with theadjacent cheeses when revolving in the creel, and restores the cheese tocentral position if displaced. WVhen' one of'the flanges 5* is on thehighest portion of the periphery 01?;13118 roller, that side of thecheese moves a little faster than the other side, and hence the cheeseis caused to cant, as a result of which the cheese moves sidewise as itrevolves until both flanges Z) are again on the surfaces 10.

As shown in Fig. 3, the surfaces 10 on the adjacent ends of the rollersextend so close to each other that there are no gaps between the rollersinto which the flanges b can drop.

The greatest diameter of the roller 2 is suificiently less than thesmallest internal diameter of the cheese core so that the latter may bereadily slipped on and off the roller by the operative.

In the construction herein illustrated, the spindles 1 are arranged ingroups of three,

each group being fixed to an. elongated base 12. Thespindles 1 aresecured to the base 12 by means of attaching members 13. Upon the outerend of each spindle is a tubular tip or cap 14 which, for convenience inmanufacture, is rotatably mounted upon a sleeve 15, said sleeve havingan outturned flange upon its inner end. The sleeves 3 are spaced awayfrom each other and from the attaching. member 13 and the tip 14 bymeans of sleeves 16 having out-turned end fie nges which abut theflanges of the sleeves 3 and 15. The series of sleeves 3, 15 and 16 isclamped against the attaching member 13 by means of a nut 17 screwedupon the outer end of the-spindle 1.

A spool 18 is rotatably mounted upon each sleeve 16. As shown in Fig. 3,the ends of the rollers2 are countersunk so as to overhang the spools18. These spools receive any yarn which may get between the rollers 2 orbetween said rollers and the attaching member 13 and the tip l't. Incase some yarn should becomewound upon one of the spools 18, the yarnmay be readily unwound therefrom by the operative, since the'spool willrotate freely as the yarn is withdrawn.

, Each base 12 with its row of spindles 1 will hereinafter be termed atrident.

The tridents are adapted to be used at the winder as a'receptacle or asupport for the cheeses when the latter are removed from the winder.When in use at the winder, the tridents restupon the bases 12' with thespindles 1 in upright position. l/Vhen in such position t-hecheesecores]; on a given spindle rest uponone another, as shown in,

Fig. 1. then the tridents are in use in the creel, the spindles occupy ahorizontal position. lVhcn the warp-beam is revolved, thecheeses movelaterally until each is properly located on its roller as shown in Figs.1 and 3. As indicated in Fig. 1, when the trident is placed in the creelframe, the cheese nearest the tig of the spindle is so positioned thatits bearing flanges b are both on the high portions of two adjacentrollers, and hence said cheese does not tend to move laterally, butthe'cheeses nearer the base 12' push said cheese laterally until itsbearing flangesare at different elevations, whereupon said cheesecenters itself upon its roller. All of the cheese cores are thenout ofcontact with each other, as represented in Fig. 1. It will be seen thatthe cheeses need not be manually placed in running position upon theirrespective rollers.

The framework of the creel may be of any suitable character. Forexample, the framework may be composed of a plurality of bays eachincluding a compartment adapted to support a plurality of tridentsarranged one above the other as fully disclosed in Patent No. 1,207,138,granted De cember 5,1916. Herein only a portion of the creel frame isillustrated. At the left-hand side of the bay is a socket 19 to receiveone end of the base 12- of a trident. At the righthand side of the bayare sockets 20 (Figs. 1 and 2) to receive the tips 14. Each bay isprovided at one side with a gate 21 hinged at 22. The gate is held shutby means of a projection 23 on the gate adapted to lie in a recess 24 ona locking member25 fixed to the creel-frame. Each gate is provided withwithout giving any attention to the matter 7 of seeing that the yarnunwin'ds from the upper part of the cheeses. v

It will be apparent that the creel, comprising as it does tridents eachofv which is supplied with twelve cheeses atthe winder, may be filledand emptiedvery quickly, andwith a minimum of handling of thecheeses;

Suitable means may be; employed to arrest the rotation of. the cheeseswhen the warperstops. Herein I have indicated .inllig. 2 brake devices27 located at the rear side of the creel-frame:andarranged to engage theperipheries of the yarn masses upon the cores 6, saiddevicesbeingsimilar to those spindles.

fully described in my copending application Serial No. 27,093, (PatentNo. 1,207,138).

It Will be evident that the construction herein disclosed simplifies thehandling of the cheeses and permits the cheeses to be rotated in theWarping process with a minimum amount of friction.

This application is a continuation in part of application Serial No.781,919, filed July 30, 1913, and application Serial No. 27,093, filedMay 10, 1915, (Patent No. 1,207,138).
